IMPROVEMENT IN BOQM AND SAIL ATTACHMENTS.

' Specification forming part of Letters Patent No. 186,603, datedJanuary 23, 1877; application filed December 18, 1876.

To all whom it may concern:

Be it known that I, FREDERICK NoRwooD,

of Gloucester, of the county of Essex and State of Massachusetts, haveinvented a new and useful Improvement in Boom and Sail. Attachments; anddo hereby declare the same to be described in the followingspecification and represented in the accompanying draw: ings, of whichiFigure l is a top view, Fig. 2 an end elevation, Fig. 3 a longitudinalsection, Fig.

Y 4 a side view, and Fig. 5 a bottom view, of

the end portion of a schooners boom with my improved sail-connectionapplied thereto. My invention isto prevent the accidents whichoccasionally result from the common.

pot-bail as generally applied to a boom that is to say, as extended fromthe side thereof. When so arranged it is very liable, when the boom isover the rail and the vessel is sailing oyand in close proximity toanother vessel, to become caught in the rigging of the latter, andthereby to do injury thereto, or to the masts or other part or parts ofsuch vessel.

With my invention the sail-connection extends up from the upper surfaceof the boom, and in no respectprojects from the side of the boom. I

In carrying out my said invention, as shown in the aforementioneddrawings, I provide the boom A, near its outer end, with two longmetallic plates, B 0, let into and fastened to it, one of them beingarranged in the upper and the other in the lower side of the boom, andboth being. secured to it by screws or other suitable appliances.Vertically through these plates and the boom 1 make a series of holes, aa a a, at equal distances apart, and in each hole of the lower plate Iform a female screw, b, to receive a male screw, 0, out on the lowerpart of the shank d of a forked bolt, D, formed and provided with aconnectionpin, E, as shown. The pin E, furnished with a head, goeshorizontally through the prongs of the furcated head 6 of the bolt, andis held in place therein by a cross-pin, f, driven diametrically throughsuch pin E, and arranged and against such plate, or a washer previouslyV placed on the bolt-shank, in which case there will'be no need offemale screws in the holes of the plate. This sail and boom attachmentaffords ready, means of adjusting the bolt nearer to or farther from theend of the boom or the sail, as occasion may require. It also insures afirm support to thefurcated bolt, and prevents it from splitting theboom under sudden drafts of the sail. It also presents f otheradvantages, which to a mariner will be easily apparent. l

I claim- 1,

The furcated screw-bolt D, its connectionpin E, and the perforatedplates B 0, arranged and combined together, and with the'boom A,substantially as and for the purpose as set forth.
